For the remaining 0.001 % that can't play MP3s, I would not worry for them.
The Mac does not rely on filename extensions, but if your audience is mainly PC/Windows then you'll want the extension.

I am sending out an mp3 voiceover demo to producers over my own website.
It was produced and uploaded with a Mac. It has an .mp3 file name.
Will it be playable on Macs and PCs? Also I notice my voiceover
studio sent it to me without an .mp3 file name. Does that make it
more universal? --Russ Nichols, Los Angeles
